Definitions
- This invention relates to a process for the removal or reduction of dissolved hydrogen sulfide, and reduction of BOD in sewer systems, municipal waste treatment plants and in other industrial waste applications.
- nitrate provides an oxygen source which promotes the growth of naturally occurring bacteria which utilize in their metabolism the sulfur tied up as hydrogen sulfide. It has been demonstrated both in lab jar tests and in an actual sewage collection system test, that dosing sewage containing over 50 mg/L of dissolved hydrogen sulfide with a sodium nitrate solution reduces the dissolved hydrogen sulfide to less than 0.1 mg/L. Along with this phenomena a significant reduction in sewage biological oxygen demand, BOD, of up to about 70%, and overall "sweetening", i.e., removal of other minor odors, of the sewage has been observed. These phenomena are believed to be the results of the biological process promoted by the nitrate addition.
- nitrate oxygen NO 3 --O
- S 2- 1 part dissolved sulfide
- an "incubation" period of about 8 to about 96 hours, and preferably about 24 to about 48 hours, is necessary to culture the bacteria, followed by about 1.5 to about 20 hours, and preferably about 3 to about 12 hours, for ongoing sulfide removal.
- the FIGURE is a schematic diagram representing a sewage system employed in the Example described herein.
- nitrate ions NO 3 provides an oxygen source for certain bacteria already present in the waste or sewage to thrive.
- the bacteria that grow as a result of the nitrate oxygen utilize the dissolved hydrogen sulfide as part of their metabolism.
- the dissolved hydrogen sulfide contains sulfur which the bacteria also require in their metabolism.
- the source of nitrate to accomplish the sulfide removal is not critical, and both aqueous solutions of sodium nitrate and calcium nitrate have been used successfully.
- the promotion of biological activity via nitrate addition as described also achieves a reduction in sewage BOD due to the utilization of organic matter in the metabolism described.
- sodium nitrate was added to a sewer system in Jacksonville, Florida at a master pump station, or feed point B, upstream of a second master pump station comprising a monitoring point A.
- the feed point B was at a point removed from an intersection C of the feed line and main sewage line, as indicated in the FIGURE.
- Average detention times (based on average daily flows, line sizes and lengths are as follows:
- the B ⁇ C distance and retention time of 7 hours constitutes the incubation period, coupled with the distance C ⁇ A and associated retention time of 3.3 hours comprises a total of 10.3 hours from addition of the nitrate station at point B to the monitoring at point A, thereby permitting sufficient time for the bacteria to culture.
- the average daily H 2 S at point B was 25-30 ppm.
- Subjective sampling also indicated a significant reduction in sewage odors other than hydrogen sulfide.
- the present invention provides for the removal of significant amounts of dissolved hydrogen sulfide and a corresponding reduction in sewage BOD.
- sodium nitrate By properly feeding sodium nitrate into the sewage or waste, odor and corrosion problems can also be substantially eliminated.
